How to achieve image edge blur effect in css
We can achieve image edge blur effect through box-Shadow attribute.
The syntax of this attribute is as follows:
box-shadow: h-shadow v-shadow blur spread color inset;

<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
